Moira with her own team of mutants and executing HER plans (even if covertly) both makes sense and sounds amazing. And given that those four had a connection with Krakoa, I want to see how it can continue (also Sway and Petra are amazing).
Maybe X-Corps would start as a spotlight episode in Marauders? Like a plot involving the Hellfire Trading Company and X-Corps could be a spinoff.
